The invention is shown applied to a cash register of the type shown inthe patent to Cleal and Reinhard granted April 13, 1897 No. 580,378,patent to Thomas Carroll granted March 8, 1904, No. 754,049, and in anapplication for patent on cash registers of E. J. Von Pein filed May 26,1909, Serial a No. 498,548. It is an improvement of'the machine shownin-the copending application for patent on cash registers of H. A.Martin filed November 19, 1910, Serial No.

The greater part of the construction, shown 1n the drawings, formingpart of ,the present application, is shown and described in the saidcopending application.

In the prior application a cash register is described having mechanismsuitable for recording commercial transactions by accumulating theamounts of such transactions in suitable totalizing devices rate printedrecords are made of transacrepresent totals of Sepations and totals maybe printed of amounts accumulated by the totalizers.

The present invention relates to a Pashregister similarly equipped,butvin addition diiferent salesmen, whereas in the present case thetotals are those of diflerent classes of transactions, namely, cash,bank deposits, checks drawn, goods delivered, bills pald, miscellaneous,recelved on account, charge, and paid out. It will thus be seen that atany period a complete printed statement of the financial condition ofthe business in which the machine is used may be obtainedwithout'necessarily resetting the totalizing device to zero.

Any desired number of counters are pro- 7 vid'ed for counting each itementered, in its nism,

proper class. In the present machine these counters may besimultaneously. reset by power applied from the main driving mechanismof the machine. w

' Such elements. of the present machine as are disclosed in the earlierapplication are here briefly described, particular attention being paidonly to the mechanism employed for accomplishing subtraction, andsubtotalizing from any of the sets of totalizers, and for resetting bymotor power all of the totalizers and accounting devices in the machine.

The machine is constructedto make separate printed records of allentries of whatever class, to total the various entriesaccording toclass, to issue a printed statement of each transaction entered, and toadd to or subtract from a cashbalance totalizer according to received orpaid out amounts, to print the totals of different classes of enteredamounts when desired, and to reset any of the totalizers or allcounters.

It is thought that the invention may more easily; be understood if thegeneral plan of the totalizers and their operating mechaand theirvarious desired operations are set out, before explaining the.construction employedto accomplish the functions provided for.

Addition or subtraction is efl'ectedin any I one of the totalizers bydifferential recipro cation of racks with which the totalizers areadapted to be connected during the initial movement of the racks.Theseracks are arranged in pairs above and belowthe totalizers with theracks of each pair in the same talizers with the-upper set sired merelyto print vertical plane. Eachpair of racks'is adapted to be controlledin its movement by one of the denominational banks of value. keys. Thus,it is possible to add an amount to the paid out totalizer and subtractthe same amount from the cash balance totalizer simultaneously, byconnecting one of the toof racks and the other totalizer with the lowerset of racks. Again, two totalizers may be simultaneously added to byconnectingthem to opposite sets ofra cks by predetermining, forconvenience of design, that addition shall be made in one totalizer by arotation opposite to that which eiiects it in the other totalizer. Thearrangement'of the racks accordingly permits a wide variety ofdifiz'erent operations of the totalizers, and does not necessitate morethan one set of transfer devices for each set of racks as would be thecase if the totalizers were simultaneously connected to the same set ofracks. Each pair of'racks also has connections to'a correspondingtypecarrier of the printing mechanism, and accordingly at each operation ofany of, the totalizers, the typecarriers are set to print the ,7 desiredamount, whet er'i't is added or subtracted from the totalizers, theimpression being made while the racksare at rest in their set positions.A totalizer is reset by backwardly rotating its pinions to zero positionthrough connections from the main driving mechanism, and accordingly,through the racks and connections the type carriers are set properly toprint a total.

If instead of resetting a totalizer it is dethe total thereon, it ispermitted to remain connected to the racks during theirrestoring-movements and thus their differential return movementretrans-. mits the amount to the totalizer pinions.

In the normal operation of the machine when transactions are entered,the totalizerdriving racks are permitted to remain in set positions atthe completion of operations, and are restored to zero at the beginningof the next operation of whatever kind. As subtotalizing requires thatthe racks be restored to normal position a second time in order toreplace the amount on the totalizer .wheels, it is necessary to'pro-videmeans for producing a second operation of the machine on such operationsto permit the required second restoring movement. A clutch mechanismwell adapted to accomplish-this purpose has been devised and isdescribed in detail further on.

To I unit'in the' type of drawings, the special transaction totalizers"are coaxially mounted and their various denominational elements arecoordinately grouped, as descnbed 1n the former application. a

The invention relates to, a type of ma-' provide a compact multipletotalizer machine shown in the chine which is varied much to suitdifl'erent requirements of users and in the present case is shownadapted for any business in which it is at all times desirable quicklyto ascertain its financial condition with respect to the cashon hand,and for definite periods,

the totals of cash taken in,bank deposits,

- checks drawn, value of goods delivered,'bills paid, cash received onaccount, charge sales, and cash paid out. One of the totalizers isassigned to accumulating amounts of. other natures than those aboveenumerated, in order that the machine may serve the purpose of anycommercial adding machine without disturbing the remaining accountswhich it is adapted to keep. The individual entries are further recordedon detail record and receipt strips and are publicly indicated. Thus thework performed b the machine is to accumulate in segregate classes.theivarious transactions entered, print records, in-.

dividually and as separate totals, and, as usual, to indicate the natureand amount of each entry.

The means employed to accomplish the.

til both a transaction and a salesm'ans keyare depressed. The depressionof these keys also serves to permit the'operation of a clutch connectingthe motor to the driving mechanism of the machine. The driving mechanismis connected first to restore the differential mechanism to normalpositiomand then to drive its various" elements difi'erent extents asdetermined by the depressed keys.

' The differential mechanism is connected to communicate its movement tothe indicators, type carriers, and driving racks for the totalizers.During the restoring movement of the differential mechanism thetransaction totalizers are properly positioned so that one" may beconnected. to the operating racks when they are .at rest in their zeropositions. The selection of the particular totalizer to be operated isdetermined by the depressed transaction key. I

Difie-rential mechanism.-'Referring to the drawings, Fig. 2 shows one ofthebanks of value keys 1. These keys increase in value in order from oneat the bottom of the bank to nine at the top. The depression of a keyserves slightly to lift a key detent 2 pivoted on the shaft and havingconnections to release a latch 3 from a retaining pawl 4; pivoted to themachine frame.

Each latch 3 is carried by a segment gear 5 journaled on the shaft 85,one ,of these segments being pirovidedfor each bank-o1. keys whether theeys represent amounts, transactions, or salesmen. A plurality of segments 6, fast to shaft 85, and having a constant oscillation at eachoperation of the machine, by engagement of flanges 600, formed onrearwardly extendingarms on said segments 6, first restore any of thesegments 5 which have been moved out of normal position bya previousoperation, to their normal position, in which the segment is shown inFig. 2. On the return movement of the member 6 shoulders 1600 formedthereon will engage any of the latches 3 which have been released by thedepression of keys and, through the latches, rotate said segments 5until the same are disconnected from the members 6 through a reverseoperation of latches 3 by engagement of arms 7, carried by segments '5,with the depressed keys. The arms 7 are suitably constructed todisconnect the latches 3 from the members 6 upon said engagement,therefore, the members 6 continue their constant movement while thesegments 5 are held in their adjusted positions.

The segments 5 are connected to the indicators through gear connections8 and to the type carriers through pins 900 on the seg- 'ments'engagin'gslotted arms 9 fast on concentric sleeves 11. The sleeves are connectedto rotate type carriers 12 (Fig. 1) located at the right hand end of themachine. The sleeves 11 surround a shaft 10 which has connections forsetting a transaction type carrier, which is one of. the type wheels 12.

Shaft 10 (Fig. 3) carries rigidly an arm 155 carrying a pin 156extending across the rear edge of an arm 911 for the bank of transaution ke s, loosely mounted on shaft 10. Thus w en the arm 911mov'esrearwardly. it engages pin 156 and, through arm 155 and shaft 10, setsthe transaction type carrier. A spring 157 extended between the end ofarm155' and arm 911 normally holds the two arms in engagement. butpermits arm 911 and segment gear 80 fast to the transaction segment .2,to return to normal position 1 independently of the transaction typerarrier. Thetype wheels are retained in set positions at the completionof operations of the machine by aliningpawls, but it is desirabletorestore the segment 80 to normal position at the completion ofoperations, as explained'further on. The spring permits such restorationand serves to restore the transaction type carrier when it is releasedfrom'the alining pawls.

The slotted arms 9. which relate to the banks of value keys are eachprovided with.

a depending segment gear 13 meshing with apinion 161 loosely mounted ona shaft 15, but rigid with a companion pinion 16 of V shaft 15 and aframe 24 fast to that shaft.

Thus, addition or subtraction as desired, may take place in thetotalizers by connecting them to either the set of racks 21 or the set22, and on such operations the totalizers are not connected during therestoring movement of the differential mechanism, but only during itsforward or initial movement.

gagement with the shoulders 34 on the racks.

The construction of the totalizer racks is best shown in Fig. 11. Eachpair of racks is mounted on the respective yoke 18 by pins 25 and 26passing through short slots 27 in the racks. Springs 28 and 29 extendingbetween pins 30 on the racks and pins 31 on the yokes, normally urge theracks 21 and 22 to the right as far as permitted by their slots 27, butare normally prevented from such movement by pawls 32 pivoted by pins 33to the yokes 18. The pawls 32 normally engage shoulders 34 of the racksand if they are moved out of engagement with these shoulders, the rackswill spring one step to the right (Fig. 11), the require distance torotate the totalizer pinions one unit of movement and thereby efl'ecttransfers. Each pawl 32 is provided with a pin 35 extending through aslot 36 in its respective yoke and through a slot 371 (Fig. 10) in anarm 37 forming part of the transfer trip mechanism. Each arm 37 'isrigid with a companion arm 38 having lugs 39 and 40 in suitable positionto be engaged by lugs 400 (Figs. 6 to 9) on the totallzer pinion of nextlower order to that engaged by the respective rack under control of arm37. The lower pairs of arms 37 and 38 are loosely pivoted on the rod 42(Fig. 14) and the arms of each pair are rigidly connected by sleeves 43forming a journal on-the rod 42. The upper arms 37 and 38 are fastenedtogether by short rods 41, and. these ,rods

are. journaled in the upper ends of the bosses projecting upwardly fromthe base frame. The pairs of arms 37 and 38 are normally urged intooperative position toward the. totalizer pinion 1 by springs 44 andthus, through the slots 36, hold pawls 32 into en- 'Such of the pawls 32as have been rocked I out of engagement by transferring operations, arepermitted again to engage-shoulders 34 atthe beginning of the nextoperation of the machine after the racks have been restored to normalposition. This is accomplished bymechanism shown in Fig. 12 comprising apair of arms 45 and 46 for each pair of racks, fast to shafts 47 and48.-

Fastened toshaft 47 is a lever 49 pivoted I to a pitman '50 at one endand to a link 51 at its other end. Link 51 connects lever 49 with an arm52 fast to shaft 48; The pitman is provided with a roller 53 in positionto'be engaged by'a shoulder 54 of a tion of arms 45 and 46 is such asnot to inracks extents determined by the value .keys.

In order to aline the racks while the totalizers are being connectedthereto, a plurality df alining pawls (Fig. 11) are provided, insuitable positions for engaging alining teeth 61 cut in the lower sidesof yokes 18. These pawls 60 are fastenedto a rod 62, journa-led in theframes of the machine, and certain of the pawls areengaged at their rearends by arms 63 fast to a rod 64, for the purpose of rockingalll of thepawls into engagement with teeth 61. The rod 64 is journaled in theframesof the machine'and has fast thereon an arm 65 pivoted at its upperend to a link 66'which, at its forward end, is pivoted to a bellcranklever 67 loose on shaft 48. One arm of the bell crank lever 67 isconnected by a link 68 to an arm of a bell crank lever 69 pivoted onshaft 47. Bell crank lever 69 at its forward at all times tosh'ow theactual amount of cash in the drawer or on hand. It follows I that it isdesirable to operate this particu- .first case it is rotated additively,whilevin the second, subtractively. Thus it serves talizers for casreceived on account lar totalizer simultaneously with the toand paidout, but for the first two of these classes of transactions the balancecash totalizer should be added to, while at paid out transactions theamount paid should be subtracted from it. It is, therefore, mountedlndependently of the remaining *totalizers, as it is at .times necessaryto connect it with one set of racks while the-selected, one of the groupof totalizers shown on rod 72 is connected with the remaining set ofracks.

The totalizer pinions are journaled on a shaft 73 mounted in the frame24 and are suitably spaced thereon by yokes 74 eaeh totalizer pinion ina vertical plane v with one of the pairs of racks 21 and 22.

Frame 24 is secured to rod 15 journaled in theframes of the machine andby suitable means prevented from longitudinal move-v ment, The rod 15also supports frame 23 of which includesone pinion in each oup in'whichis fastened shaft 72 sup "the totalizer pinions 19.

porting The pimons 19 are prevented from sliding along shaft 72 bysuitable spacingcollars and frame 23,

. .but' frame 23 is-free to be shifted along- 7 rod 15 and also tooscillate thereon.- The pinions 19 constitute nine totalizers, each ofpinions as appe'ars m ,Fig. 5,'and me 23' has. fast thereon a screw 77having threads co-acting with internal threads on a rotatable nut 78. Byrotating nut 78 the fram'e 23 may beshifted to bring any one of thetotalizers into the .planes of theactuatingracks2liand 22 to be actuatedthereby;

Cam 90 is angularly positioned .on shaft 56 to effectthe restoringof segment gear 80 (Fig. 3) near the-end of the operationof the machine rather than at the beginning, as is the case with segmentgears 5 (Fig. 2). The segment' gear 80 carries a pin 800 for engage-.ment by the flange 600 of. its respective totalizer frame will be rockedupwardly 90 around; its supporting rod 15 theieby meshing the totalizerpinions20 with the 'set of racks 21 (Fig, 2), whereas if plates 93 arerocked forwardly the totalizer pinions 20- will ,bemesheiiwith the lowerset of racks 22'. It isbythis means that addition is effected. in onecase; when the ,pinions are connected to the'vu'p'per set of'iiacks,while sub traction or resetting may be effected in the other case whenthe pinions are connected 1.00

to the lower set of racks. c The totalizersq-mounted on rod 72 are'similarly controlled as to the mechanism -.foriconnecting them to thedriving racks, the rod72' pami'ng through eccentric slots 1 95in plates96' fast to a shaft 97. Thus, if

'thelplates96 are rocked forwardly, the totalizer pinions will belowered into connection with the lower setof racks, but whentheyarerocked rearwardly the pinions will be reverselymoved intoconnection with the upper set of racks.

mounted on a link' 337 pivoted at its rear end to an arm 338 on a shaft339, and guided which shaft 97 .passes. Shaft 339 has secured thereon anarm 341 to which is pivoted a pitman342having a pin 343 extending'into agroove on the outside of cam 100 fast to-sh'a-ft 76r, -The cam serves tolower pitman 342 and hold it in its lowered position for a suflicientlength of'time to-permit the totalize'rs to be operated. When the pitmanis moved downward, through shaft 1 339. and arm 338 it moves link 337;to the 130 at its forward end by its slot 340 through 336 from theco-actmg arms'fastjto shafts 94 and 97'. Also rigidly fastened to shaft339 is an alining arm 345 adapted, when the pitman is lowered, to engageteeth 346 (Fig. cut in the frame 23 transaction totalizers. By thismeans the selected totalizer pinions are correctly alined with the racks21 and 22.

The mechanism employed for determining whether selected totalizers areto be connected with the upper or with the lower sets of racks, iscontrolled by the bank of transaction keys, except at total printingoperations, rate manually operated lever to be described further on. Theupper set of racks serve for addition in the cash balance totalizer andin the paid out totalizer: The remaining totalizers are added to by thelower set of racks. -By this arrangement simultaneous addition may takeplace in the cash balance totalizer and in either the cash or receivedon account totalizers. Also, as

the paid out totalizer is added to by the.

drive shaft 76. This shaft makes one rotation at ea'choperatio-n of themachine in a direction indicated by the arrow, and is provided with acam groove 101 acting on a roller 102 carried by the downwardlyextending arm of a bell crank lever 103, journaled on a stud 104 fixed-in one of the sup'- ,porting'frames of the machine. Groove 101 issuitably formed to oscillate bell crank lever 103 once during anoperation of the machine and serves at the required time to 'cause' a Vshaped plate 105 pivoted at 106 to the forwardly extending arm of thebell crank lever, to move downwardly. The two'arms 107.an'd.108 of'theplate 105 are respectively provided with notches 109 .and

110 for engaging pins. 111 and 112 on'a. beam 113 fast to a sleeve 114surrounding a fixed rod 75. 1 Normally slot 109 engages pin 111,'thus onthe. downward movement 0 plate 105 sleeve 114 will be rotated'slightlyin a clockwise direction and thus, through a beam 115- (Fig; 4) .fast onsleeve 114, a

itman 116 will v 117 will be lifted, as these "pitmen arerespectively'provided with notches 118 and 119 normally. engagingpi'ns120and 121 on the ends of lever 115. Such anormal operation would occuron the depression of either the cash or received on account keys, whichhave noconnectionst0alterv the 0p-- right, thus disengaging the teeth335 and which supports the when it is under the control of a sepa- -saryto reverse out key 128. a link 129 to lever 130 loosely journaled on rod75 and provided with a slot 131 through flowered while 'a 'pitmaneration. This downward niovement of pitman 116 (Fig. 4) causes thetotalizer pinions 19. to be lowered, thus meshing either the cash orreceived on account totalizers with the lower set of racks. The

ing plate 93 counter-clockwise, lifts the f cash balance totalizerpinions into mesh with the upper set of racks. Then, upon thedifferential movement of yokes 18 (Fig. 2) under control of thevalue'keys; racks 21 will add the amount represented by the depressedvalue keys to the cash balance totalizer and to the selected one of thegroup of transaction totalizers.

It was previously mentioned that addition takes place in the paid outtotalizer by the upper set of racks, consequently when the paid out keyis depressed it is necesthe operation of pitmen 116 and 117, that thepaid out totalizer may be added to while the cash balance totalizer issubtracted from. In order to accomplish this the paid out key hasconnections to'the V shaped plate 105 (Fig. 3) that it may be rocked onits pivot 106 so upward movement of pitman 117, by rockthat notch 110engages pin 112 of lever 113.

This function is accomplished by rockingpitman 117'forwardly a slight distance around its pivotal connection toplate 93, so that its notch- 119 becomes disengaged from the pin 121 onlever 115, and then when lever 115 is rocked it has .no effect on pitman117. A spring 133 (Fig. 4) 'nprmally retains the pitman 117inengagementwith pin 121, and to rock it out of engagement with this pinan arm 134 fast to a shaft 135 is rocked into engagement with apin165 onthe pitman. This arm 134 receives its motion from the transaction keysjust named through a segmental plate 136' (Fig. 3) having inclinedextensions 137 in the path of pins 138 on said keys. The depression ofone of the keys therefore serves to lift plate 137, and through a link139 pivoted thereto and to an arm 140 fast on shaft 135, rocks 7 theshaft in a clockwise direction, and thereis substantially the same inconstruction as having the transactions in charge.

In the present case the multipletotalizers are described as intended for receiving amounts according tothe different classes of transactions, whereas in the previous case themultiple totalizers were described as in- .tended for receiving amountsclassified in different totalizers. according to theclerks This changeinvolved a rearrangement of the totalizer'meshing mechanism in orderthat desired ones of the totalizers could be added to or subtracted fromas required.

The transfer mechanism, controlled in its operation by the multipletotalizers, is also substantially the same as that shown and describedin the aforesaid Martin application, it being altered only as requiredby the new use to which the multiple totalizers are put. As certain ofthe totalizers are-both added to and subtracted from on the differentoperations; it .isnecessary that they be constructed to control thetransfer mechanism whether in mesh with the upper or lower sets ofactuating racks. For this purpose the totalizer pinions-are providedwith two sets oftripping lugs at suitable angular locations on thepinions to trip the transfer elements at the required times. -The twolugs (Fig. 12) on any one pinion are not in the same plane soconsequently the lug which operates during addition would not trip thetransfer mechanism on a subtracting operatrol of but one totalizer.

As the totalizer pinionsare re-.

for rocking the pitmen 116 and 117 (Fig.

4) around their pivots, is provided. This means comprises a manuallyoperated seg-.

ment gear 141 meshing with a pinion 142 loosely journaled on a shaft 76,mounted in axial alinement with drive shaft 56, but rigidly connectedby'a sljeeve 143 (Fig. 17) to a pair of cams 144 and 145. Cam *144 isprovided with a groove 146 indicated by the heavy broken lines in Fig.-4, into which extends a pin 147 on pitman 116, and cam 145 is providedwith a groove 148, shown by light broken lines in the drawings, and intowhich extends a pin 149 on pitman 117.

Thus, by differentially rotatingthese camsthrough the lever 141, thedirection of operation of either pitman may be reversed,

while the other one is made entirely inoperative. The manually operatedsegment or lever 141 is loosely pivoted on shaft 85 and is provided witha spring pressed thumb grip or latch 150 adapted to enter notches 151 ina fixedplate 152, thus serving either to hold the segment 141 in itsnormal position or in any one of its set positions. When latch 150engages the lowest notch 151, cams 144 and 145 are held in normalinoperative positions, their grooves being suitably formed to permit thevertical reciprocation of pitmen 116 and .117, as required for the entryof items. When the segment 141 is rocked upwardly and its latch 150engages .the second or third notches, the cams are suitably positionedfor printing the total accumulated by the cash balance totalizer. Ifthe. latch engages the third notch the total will be printed withoutpermanently resetting the totalizer, whereas if it
